The RNAComposer system offers a new user-friendly approach to the fully automated prediction of large RNA 3D structures.
The method is based on the machine translation principle and operates on the RNA
FRABASE database acting as the dictionary relating RNA secondary structure and tertiary structure elements.

RNAComposer works in two modes:

interactive mode - allows to work on one RNA molecule
of interest at a time; its use is limited up to
500
nt residues and results in a single 3D-RNA structure model. Input your RNA sequence
and secondary structure
(Example 1 and Example 2)
or sequence only
(Example 3). Example
3 is offered for introductory purposes.

batch mode - is designed for large-scale automated
modeling of RNA structures up to
500
nt residues, based on user-defined RNA secondary structures. As an input a set of
up to
10
RNA sequences can be used. This mode is available only for registered users.
